Ultra-realistic professional studio headshot from a photo

Using the uploaded photo as the facial identity reference, create an ultra-realistic professional studio headshot while preserving the subject's exact facial identity, facial structure, skin tone, hairstyle, eyebrows, eyes, nose, lips, ears, jawline, expression, body proportions, and all natural features. Do not beautify, stylize, age, or alter the person's appearance in any way. Replace the casual clothing with a perfectly tailored premium black business suit featuring a modern slim-fit blazer over a crisp white dress shirt with the top button open (no tie), creating a clean, confident, executive appearance. Position the subject facing directly toward the camera with perfect eye contact and a calm, confident, approachable expression. Maintain a natural posture with the shoulders squared and relaxed. Use a luxury professional photography studio setup with a smooth charcoal-to-dark grey gradient background, soft cinematic lighting, a large octabox key light positioned at 45 degrees, subtle fill lighting to eliminate harsh shadows, and a gentle rim light to separate the subject from the background. Create soft catchlights in the eyes for a premium corporate portrait look. Ensure realistic skin texture with natural pores, accurate colour grading, balanced contrast, and true-to-life skin tones. Avoid excessive skin smoothing or artificial retouching. Capture using a full-frame Sony A7R V camera with an 85mm f/1.4 GM portrait lens at f/2.0 for exceptional sharpness on the face and a beautifully blurred background. Focus precisely on the eyes with shallow depth of field. Frame the portrait from the chest upward, leaving comfortable headroom and centring the subject perfectly for profile-picture use on LinkedIn, X, Facebook, Instagram, and other professional social media platforms.
